Hartford County is CT's largest county and served entirely by Eversource CT. West Hartford, Glastonbury, Simsbury, Farmington, and Avon are among the most solar-active communities in the state — high income, large homes with southern exposure, and consistent Eversource rates make economics compelling. Eversource RSIP blocks are available throughout Hartford County. Solar installer competition in this region is strong, which keeps prices competitive.

No — Connecticut law (CGS § 12-81(57)) exempts residential solar from property tax assessment for 15 years. In high-tax CT towns, this exemption is particularly valuable.
